Yes, it's true...There is a series of 8 pins near the Q chip which
correspond to raw Q-chip pins...some are used for selecting the output
channel, some are for the output itself, and one is for A/D input...
i don't have the technical details right here... when I get back to my
room I will type in the schematic for a simple A/D converter circuit to
hook into the pins... (It's in the Apple][gs Technical Reference (not
the one from Apple)...
